Comment 5 for bug 262767

Jeroen, I think you are mistaken here. Soyuz "custom" upload is an actual upload of the tarball which contains translations (I am not sure if it contains full source code as well, but that's not really relevant). If debs actually included PO files, that'd be very weird, and they'd have to be there without being installed, but would still take a lot of disk space on Ubuntu live CDs eg.

Also, while debs are based on tarballs, they are not really ones. They are tarballs wrapped with some binary data (or something like that), so our code wouldn't even work if this was the case. FWIW, I've tried and even tarfile.is_tarfile() returns False for .deb files.
